Default Re: Another (possibly silly) valve question

There's not much evidence that cathode poisoning ever happens to a significant extent in normal domestic valve circuits.

The subject seems to exercise the valve audio people a lot. I suppose if you've just paid £1,000 for a pair of PX4s you don't want to take any chances.
